B2K's "Bump, Bump, Bump" featuring P. Diddy dances its way to the top of Billboard's Hot 100 thanks to a major spike in radio airplay. The single moves up one notch to end the 12-week run of Eminem's "Lose Yourself," which tumbles to No. 9, the largest fall by a chart-topper since 1989, when Phil Collins' "Two Hearts" fell to No. 10.

"Bump, Bump, Bump" worked its way to the top of the chart over a 10-week period, and is performing slightly stronger on crossover radio than it is in urban markets. The cut is at No. 3 on Billboard's Hot R&B/Hip-Hop Singles & Tracks count, behind R. Kelly's "Ignition" at No. 2 and Aaliyah's "Miss You," which is No. 1 for a second-straight week.

Even though "Lose Yourself" is one of three songs to fall out of the top-5 of the Hot 100, don't feel too bad for Eminem, as his "Superman" is the chart's top debut at No. 55. Also on the downslide is Nelly's "Air Force Ones" featuring Kyjuna, Ali & Murphy Lee, which slips five slots to No. 7, and Jay Z's "'03 Bonnie & Clyde" featuring Beyonce Knowles, which dips one to No. 6.

Christina Aguilera's "Beautiful" is quick to take advantage, fluttering 4-2, while Justin Timberlake's "Cry Me a River" storms 8-3. Avril Lavigne's "I'm With You" continues its airplay gains and scoots 7-4. "I'm With You" is the second cut from Lavigne's Arista debut, "Let Go," to reach the top-5, and third in the top-10.

Ja Rule's "Mesmerize" featuring Ashanti breaks into the top-10, rising four spots to settle at No. 8. The track moves 10-6 on the Hot R&B/Hip-Hop Singles & Tracks chart, and is up to No. 2 on Billboard's Hot Rap Tracks tally, challenging "Air Force Ones" for the top spot.

The Hot 100's fastest-growing track at radio is 50 Cent's "In Da Club," which cruises 27-16. Meanwhile, the artist's "Wanksta" moves 29-22, and both cuts are in the top-10 of the Hot R&B/Hip-Hop Singles & Tracks chart.

The Hot 100's fastest-growing track at retail is Kid Rock's "Picture" featuring Sheryl Crow/Allison Moorer, up 24-19. It's the second-week in a row the song has been No. 1 on the Hot 100 Singles Sales tally. Oddly enough, in country markets, it's No. 1 on Billboard's Top Country Singles Sales chart for a 10th week, but is hanging down at No. 50 on the Hot Country Singles & Tracks chart. On the latter, Mark Wills' "19 Somethin'" is No. 1 for a fourth-straight week.

Other notable entries on the Hot 100 are Amanda Perez's "Angel" at No. 64, Coldplay's "Clocks" at No. 67, the Dixie Chicks' "Travelin' Soldier" at No. 70, Shania Twain's "Up!" at No. 73, and Phil Collins' "Can't Stop Loving You" at No. 76.

Over on Billboard's Modern Rock Tracks chart, Saliva's "Always" knocks the Foo Fighters' "All My Life" from the top after a nine-week reign. On the Mainstream Rock Tracks tally, 3 Doors Down's "When I'm Gone" rules for a 10th-straight week.
